This reminds us of the “FoT (Fart of Things)”, which puts a “fart” in all things. If this “small fart system” is adopted for professional baseball, the game will be more complicated, such as “fart in front of a batter” and “a few dozen fart while flying”.

It is a vending machine for “Umaibo” (snack sticks) made by  Umaibo loving “Fu-chan”.Because there are individual differences in shape in the bag umaibo and confectioneries struggled to make a mechanism to put out stably without clogging, and repeated trial and error about 20 times. I also struggled with the coin feeder.

Realizes umaibo vending machine using a simple liner motion of a solenoid. There is no waste in design, such as a coin discrimination mechanism. This work shows the importance of dropping an interesting idea into somethingworks properly.

A fun robot that stabs a dagger into a barrel with a crapper toy and enjoys the reaction of jumping out.Crapper claps when you put a dagger into the eight holes. The first feature of the crappie crisis is that the solenoid is used as an “input mechanism” instead of the conventional “output mechanism”. The solenoid operates the iron core by applying electricity to the coil. Conversely, by returning the iron core to the coil, a slight current is generated. The current is measured by Arduino and used as the “input mechanism”.

A game toy that uses a solenoid as a switch. The design and finish of the sword and barrel are also excellent, and there is a perfection as a thing. If you generate power by stabbing a sword and the character pops out, you do not need batteries?

We made a machine for walking and running in the past.
It is not tired enough to move on the land this year and it advances to the water! Extend the stroke of the solenoid with the gear and the rack, and push forward all to move forward.
Ahiru-chan is going bravely boldly without being ashamed of the name inherited from the Victoria who has traveled around the world! Have a look at how the cute little Ahiru-Chan crawls through the oars!

Every time, Sendai National College of Technology makes a moving machine with the mechanism idea of a solenoid that pulls the tide. This time from the ground to the water. Although it is an inefficient mechanism that makes you want to think “That’s impossible!”
That is lovely again.

Solenoids are attached to the Mini 4WD to enable drifting. Using solenoid number is CB07300170. I use two micro: bits for remote control. When I remotely control the solenoid on the side of the Mini 4WD, the body of the Mini 4WD slightly tilts and drifts. It was possible to radio-controlled in the state of mini 4 wheel drive (all tires are connected to the motor). Next I want to try jumping.

If attached to the existing Mini 4WD, the Mini 4WD, which was only straight ahead, moves from side to side with the radio control operation! If you combine this with a battery that can be turned on and off remotely, you can start and brake! You can upgrade your love machine!
How about Tamiya-san?

My parents and I go to bed in one room. When I go to the bedroom after finishing the task, on both sides of my futon, a great chorus of “snoring” every day. ! ! ! ! This gadget solves such troubles in the way “Pinch their nose” you often see it in dramas and animations.

A device that can stop snoring perfectly, but you do not want to wear it perfectly. However, in the future, it will be possible if the solenoid is becoming increasingly smaller and lighter, and it will not feel uncomfortable even if it is worn on the skin. It used to be a big TV monitor, but now it’s thin.

Create a mechanism to move the solenoid by the plain method of “hardening the paper with adhesive”, and the robot throws a spoon. “It is easier if you use plastic boards and wood … Brother … …” and finished with the brother also want to throw a spoon, but this method seems to be popular around elementary school children.
